Over the last 15 months Cisco has revolutionized how organizations provide reliable, secure access to end-users and devices that connect via wireless, wired or VPN networks. This new approach to unified access delivers significant operational improvements by delivering One Policy, One Management, and One Network. However, operational improvements are only half of the story. As a key solution within the Cisco ONE Enterprises Network Architecture, Cisco Unified Access allows IT to shift from merely managing the network to driving business change by delivering new connected experiences.

Business Innovation Starts with Mobility

IT is looking beyond just securely onboarding mobile devices to now scaling the access across devices. The goal is to provide the best possible user experience for rich media applications while managing the applications and content on these devices. Mobile device use continues to grow and the bandwidth required by the applications on those devices is likewise increasing. Higher mobile density, and the need for an infrastructure that can handle it, is becoming a necessity: Read More »

As enterprises are consolidating their IT infrastructure into private cloud (enterprise data-centers) or public/hybrid clouds they’re realizing massive economies of scale in application deployments. Further, they’re taking advantage of XaaS (Software/Infrastructure as a Service) offerings from Cloud Service Providers with Pay As You Go models that increase the speed of deployment and the agility of their business critical applications. This is a major shift in how applications are now being delivered over the WAN to their end-users in branch offices and on mobile/BYOD devices. IT consolidation and virtualization in the data-center are placing a lot of requirements on the enterprise WAN. Business agility and end-user and customer application experience are imposing critical requirements on the WAN. The major challenges that enterprises are facing with cloud migration are: Read More »

In my previous 3-part blog series I discussed the challenges in the Enterprise WAN and relevancy of SDN in overcoming these challenges and how Cisco ONE Enterprise Networks Architecture addresses these WAN challenges. In this blog post I will discuss how Cisco ONE (Open Network Environment) and ONE Enterprise Networks Architecture fit together. In a following blog, I will discuss how Cisco ONE Enterprise Networks Architecture provides six significant benefits to enterprises through programmability. ONE + ONE = 6 is the new math for Enterprise programmability!

Cisco ONE (Open Network Environment)

Cisco ONE is a comprehensive, Cisco wide solution (not just data center) approach to making networks more open, programmable, and application-aware. There are numerous blogs, and videos about Cisco ONE that can be found here. As a brief summary, Cisco ONE comprises of 3 pillars that provide a programmable approach to both physical and virtual infrastructure: Read More »

In my last two blogs I discussed the challenges Enterprises are facing for their WAN, the differences between Enterprise needs in their LAN and WAN, and how the traditional ONF model for SDN isn’t practical for the Enterprise WAN. Let’s now look at how the new Cisco ONE Enterprise Architecture can address this.

In my last blog I introduced challenges Enterprises are facing in their WAN deployments and the definition of ONF SDN. While the broad definition of ONF’s SDN architecture implies many theoretical answers to these challenges, we need to be pragmatic. Let’s take a look at the practical differences in LAN and WAN networks that affect how you’d deploy SDN on each. Read More »
